Telnet and File Uploads

Hi All

Is there any way to use Telnet (or its more secure cousin - SecureCRT) to upload scripts from my local machine? It would be nice to move away from FTP if possible.

Thanks very much. Smile

You can use FTP through Telnet/SSH

While logged into your SSH account, type:

ftp <enter>

ftp> open <enter>
ftp> (to) www.yoururl.com

Then it will say something like:

Connected to www.youruurl.com.
220 ProFTPD 1.2.0rc3 Server (Paul's FTP Server) [66.59.133.14]
Name (www.yourserver.com:admin):

I can't think of any other efficient way.

Re: Telnet and File Uploads In reply to

There is a program called "scp" which copies files over ssh. For example, on my system I can run the command:

Code:

scp jagerman@jagerman.com:ss.jpeg ss.jpeg

And, after asking for my password, it will copy the "ss.jpg" file from my home directory on jagerman.com to my local computer, using ssh.

The catch is that I don't have SecureCRT installed on my computer, so I can't tell you whether or not SecureCRT supports secure copying like this.

Okay, I tried what Paul suggested using SecureCRT, and I managed to connect. Here's what I got:

In Reply To:

Then, I typed "ls" (without quotes) thinking that I would be shown what files are available at that location, and I was given the following:

Honestly, I don't have a clue what just happened.

I don't know where the copies of those files went (or even which direction), and I'm not sure how to navigate to files on my local windows machine to upload them to my remote server while I'm in the ftp mode.

Am I at least somewhat going in the right direction?

Many thanks for your help. Smile

Re: Telnet and File Uploads In reply to

That is fine, you didn't delete anything...

You either use ls or dir to list files and directories within your current directory.

Use cd to change directory

Use get and put to transfer file

You can type help for more info.

Re: Telnet and File Uploads In reply to

Using a a text based ftp program to access the computer you are working on seems like a lot of work.

I graphical ftp client would do the same thing.

Re: Telnet and File Uploads In reply to

Okay, I think I'm almost there. I got in, opened ftp, then here is what happened next:

In Reply To:

ftp> open
(to) www.mysite.com
Connected to mysite.com.
220-
220-Welcome to mysite.com!
220-
220 mysite.com FTP server (Version wu-2.5.0(1) Wed Aug 25 18:14:49 GMT 1999) ready.

230 User userid logged in.

ftp> get

(local-file) /home/mysite/www/testcgi/
local: /home/mysite/www/testcgi/ remote: C:testtest.html
200 PORT command successful.
550 C:testtest.html: No such file or directory.

What I thought I was doing is directing the server to a file on my local machine and then telling it where to put it on the server. I know for sure that both of the things that I entered as (remote-file) and (local-file) exist, but I keep getting the "550" thing - no such file or directory.

In Reply To:

550 C:testtest.html: No such file or directory.

I'm also not sure why the C:\test\test.html file gets scrunched up to look like C:testtest.html

I know I'm close, and man this will be great if I can do it. In fact, this is the kind of thing that everyone should know.

BTW, once I get this thing figured out, how would I change the transfer mode from binary to ascii? It seems to default to binary and not offer options.

Thanks, again, for your help. Smile

Re: Telnet and File Uploads In reply to

Hi,

If your server supports it, just ssh into your server and then type:

rz

at the prompt and SecureCRT will pop up a file upload box, enter in the files you want to upload and hit send.

You can download by typing:

sz filenam.txt

and it will download the file. If you don't have the rz/sz tools installed, ask your ISP to put them on! It's so conveienant (and secure as it all goes through ssh, where ftp is plain text).

Cheers,

Alex

Re: Telnet and File Uploads In reply to

Wowsee, wow!

It works!

Okay, let me add a little to Alex's comments:

1. After you ssh into the server, first NAVIGATE TO THE DIRECTORY that you want to upload the files, etc., to. If you simply ssh in and don't navigate, you'll upload your file to the top level that you have permissions to enter.

2. On my SecureCRT 3.1, I don't have a "Send" button. Rather, after I type in rz and then press enter, I get a window with 2 boxes, one upper, the other lower. In the upper box, you navigate on your local machine to the file that you want to upload, then next to the lower box there is a button that says, "Add". You can either double click the file in the upper box to auto-add it to the lower box, or you can single click in the upper, and then hit the Add button.

It doesn't upload/download whole directories, like FTP, but you can add multiple file selections, at least in upload.

In either case, once I've added all the stuff that I want to upload, I simply hit the "Close" button, and then the upload takes place automatically.

Super!!!!!!!

So:

1. ssh
2. navigate to the receiving directory on the server
3. type in rz and then hit enter
4. navigate to the files on your local machine that you want to upload
5. add them to the box
6. hit "Close"

My guess is that you probably have a more recent version than I do, Alex. That's why I'm including what worked for mine.

Man, I've been needing something like this forever. I hope that everyone can take advantage of this now EZ-2-USE way of uploading securely.

I also have a question about the sz command. I first navigated to the remote file that I wanted to download. Then I typed in:

sz test.html

and then hit enter. The thing downloaded, but I was never given any download options. I found the file in the download directory in the SecureCRT directory:

C:\Program Files\SecureCRT\download\test.html

...just in case you want to know where the heck it went.

Also, what about the transfer mode? Ascii or binary? In either the upload or download, I didn't get any options.

Thanks, one and all!!!!

Re: Telnet and File Uploads In reply to

Hi,

That's the best thing about SecureCRT is it's built in support for zmodem transfer (sz and rz stand for send zmodem, receive zmodem).

It transfers all the files in BINARY mode (i.e. no changes to the file). So if you upload a perl script with windows line feeds, you'll need to change it to unix linefeeds first. You can do this with:

perl -p -i -e 's/\r\n/\n/g' filename.cgi

which will replace windows linefeeds with unix linefeeds on filename.cgi.

Cheers,

Alex
